OMX.broadcom.audio_splitter

The conformant audio_splitter component accepts audio frames and forwards these onto enabled output ports. The audio input port should be configured with the correct port and PCM settings, and then enabled. At this point the port and PCM settings are copied to all output ports and a port settings changed message is sent on all output ports.

This component has basic functionality, but is more a placeholder for future development. Plans for the future include providing logic to discard data on output ports that fail to provide a buffer to accept the data within a reasonable timeframe, provided a clock is connected. There is some support for output ports having different buffer sizes than the input port, but this is not yet fully available to an IL client.

Port	Index	Notes
260	OMX_IndexParamPortDefinition	Query / set the port parameters for the clock port. Currently this port is not advertised so should not be used.
261	OMX_IndexParamPortDefinition	Query / set the port parameters for the audio input stream, which must be PCM non-encoded audio. nBufferSize must be at least 256 and defaults to 32768, and must be a multiple of 32. nBufferAlignment must be at least 32.
	OMX_IndexParamAudioPcm	Query / set the PCM parameters of the audio input stream.
262 263 264 265	OMX_IndexParamPortDefinition	Query the port parameters for output ports.
	OMX_IndexParamAudioPcm	Query the PCM parameters of the audio output stream.
261 262 263 264 265	OMX_IndexParamAudioPortFormat	Query / set the port format used on audio ports. Currently this component only supports raw PCM on all audio ports.
